Kumar(2014)[1] find out the compressive strength of hollow blocks with partial and full replacement of sand by quarry dust. After replacement he found that 50% replacement of sand gave high strength and 100% replacement of sand gave low strength. Ernesto S. Fortes, Guilherme A. Parsekian, and Fernando S.

Jul 28, 2018· A quick answer Yes. 'Hollow Bricks are generally good. Studies show that hollow bricks or blocks have greater advantages than the solid bricks. Both clay hollow bricks and concrete hollow bricks have enough proven benefits but the former having much more than the later. Recommended read .

flyash . However the specimen of size 230mm x 110mm x 90mm were cast for different mix percentage of Flyash (15 to 50%), Gypsum (2%), Lime (5 to 30%) and Quarry dust (45 to 55%), compressive strength were studied for different mix proportions. The results shows the variation of compressive strength for
